Encoder 1 Rotation
Selection
Sets the output sequence for the A and B pulses from the encoder,
assuming that the motor is operating in the forward direction.
0 : Pulse A leads in FWD Direction
1 : Pulse B leads in FWD Direction

F1-06
(0385)
Encoder 1 Pulse
Monitor Scaling
Sets the ratio between the pulse input and the pulse output of the
encoder as a 3-digit number. The first digit is the numerator and the
second and third digits set the denominator.
The dividing ratio = (1 + x)/yz when the setting value is a 3-digit
value (xyz).

Overspeed
Detection Level
Sets the detection level of oS [Overspeed] as a percentage when the
maximum output frequency is 100%.

Encoder 1 Gear
Teeth 1
Sets the number of gear teeth on the motor side. This parameter and
F1-13 [Encoder 1 Gear Teeth 2] set the gear ratio between the
motor and encoder.
